This paper presents a method to estimate the parameter of permanent magnet synchronous motor using a least squares method. The
approximate solution of the linear
simultaneous equations is obtained by the pseudoinverse least squares method of
the input current
and output voltage data of the current
controller. It is possible to obtain the current response of the same bandwidth
to the general
control target by using the Pole-zero
Cancellation technique. This paper verifies the performance of the proposed
method by
comparing the results of estimation of
parameters of different motors by simulation.
